Ocean margin sources such as continental run-off, sediments and hydrothermal vents are key sources of iron and other essential nutrients. Currently, climate change is impacting many of the margin processes that determine nutrient fluxes to the oceans, such as accelerating glacial melt and changing circulation patterns. These effects have the potential to limit or enhance marine productivity, with consequences for higher trophic levels, carbon drawdown and sequestration.

At many ocean margins, fluxes of trace metals are poorly constrained, owing to a lack of information with which to accurately assess supply rates. My research uses radium isotopes, a powerful approach for constraining input and removal of iron at different margin sources. Radium decays over time after release from sediment, making it an ideal chronometric tracer of ocean margin processes.
